Wow, so happy to find a geraniumm forum. I just love geraniums and have been growing them for over 25 years. A few weeks ago, I noticed the edges of my geranium leaves turning a maroonish-pink color. Could this be the food the nursery fed it prior to selling. THese are in a plastic pot and I had planned to remove them and plant them separately in my garden, but am wondering if I should proceed.

Any help in diagnosing this mystery will be appreciated.
